As discussed in [1]}, a gating mechanism is needed to assign various attentions to different view features. We utilize an FC-ReLU-FCIn our implementation, FC is achieved by using a \(1\times 1\)  convolution. layer with a sigmoid activation as the gating mechanism to aggregate information across all views, which is defined by
\(w=\sigma (W_{2}\ast \delta (W_{1}\ast z),\)
